Perhaps you should try some spelling variations:
"by computational java java programming" » "by computacional java java programming" (Expand search), "by computational data java programming" (Expand search), "by computational and java programming" (Expand search), "_ computational java java programming" (Expand search), "and computational java java programming" (Expand search), "by computational java and programming" (Expand search), "by computational java based programming" (Expand search), "by computational java goal programming" (Expand search)
"using visual python python programming" » "using via python python programming" (Expand search), "using visual path python programming" (Expand search), "using visual pythons python programming" (Expand search), "using visual piton python programming" (Expand search), "using visual pitons python programming" (Expand search), "using virtual python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computational java java programming\") OR (\"using visual python python programming\"))~".
• Removing quotes may allow a broader search: (( by computational java java programming ) OR ( using visual python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computational java java programming") OR ("using visual python python programming"))*.
